Other claims from this paper (10)
- Observation Nurseries produced grapevines with distinct endospheric microbiomes that converged over time but remained significantly different after three years.
- Observation Microbial turnover after planting was much faster in belowground compartments (root and rhizosphere) than in trunk compartments.
- Observation 15% of the initial microbes persisted in the three-year-old vineyard.
- Observation The fungal pathobiome, partly inherited from nurseries and associated with vascular diseases of trunk and root, was also clearly distinct after three years.
- Observation No typical disease symptoms or vine death were observed during the experiment.
- Observation Vineyard yield was highly variable among clonal vines.
- Association Regression models using the top ten high-impact ASVs accounted for 51% of yield variation in trunk compartments.
- Association Regression models using the top ten high-impact ASVs accounted for 60% of yield variation in belowground compartments.
- Observation 16 of the 19 yield-associated ASVs originated from nurseries.
- Recommendation The authors suggest that the nursery life stage could be leveraged to engineer the grapevine microbiome and improve vineyard resilience.
